HOIST.

Application filed March 13, 1919.

To all whom it may concern:

Be it known that I, IVALTER M. PHARES, a citizen of the United States,residing at San F rancisco, in the county of San Francisco and State ofCalifornia, have invented new and useful Improvements in Hoists, ofwhich the following is a specification.

The object of the present invention is to provide a simple and cheaphoist for raising and transporting heavy objects, which can be operatedat comparatively small expense.

In the accompanying drawing, Figure 1 is a side view of my improvedhoist; Fig. 2 is a plan view thereof; Fig. 3 is an enlarged verticalsection of the pivot of the hoist.

Referring to the drawing, 1 indicates a car mounted upon rollers 2,which can run upon rails 3 of a track, and having a hollow sphericalmetal top or fulcrum 41. Extending over said top is a beam 6, which may,for instance, be composed of three bars 7, of square cross section,bound together at suitable intervals by straps 8. Secured to said beam 6directly over said top 4: is a post 9, the top of said post being tiedto the ends of the beam by a tie-rod 10 extending in a groove 11 in thetop of the post and attached at its ends to straps 12 around the ends ofthe beam 6. From the strap 12 around. the end of the longer arm 13 ofthe beam depends a loop 14 from which is suspended a rope or cable 16which is used to encircle any object, such as a block of granite, or thelike, to be raised and transported to another position. Upon the end ofthe shorter arm 17, of the beam is secured a platform 18 which is of awidth gradually increasing from its inner end adjacent to the fulcrum 4to the outer end adjacent to the outer end of the beam. The weight ofthis platform Specification of Letters Patent.

a round head 20 permitting the beam to rock upon said round fulcrumwhile retaining it in contact therewith.

Vvhen it is desired to transport a heavy object, such as a block ofgranite, from the place where it lies to another place, as a truck orcar, the cable or rope 16 is first secured around said block and thenthe operator places upon the platform in succession a sufiicient numberof bags 21 of sand to counterbalance the weight of the block so thatboth said block and said platform are suspended in the air, as shown inFig. 1.

The operator then moves the beam horizontally upon the fulcrum, and, ifnecessary, adds further weight to the platform to raise the block to asul'iicient height to deposit it in the truck or car in which it is tobe placed and then swings said beam until said block is over said truckor car. He then allows the block to descend, either by applying manualforce to either end of the beam or by removing some of the weight on theshorter arm of the beam. The cable is then removed from the block andthe beam swung back again out of the way of the truck or car and isready for another operation.

The advantage of the device is that it is comparatively simple inconstruction, re

quires but few parts, and is also simple and inexpensive in operation,since it requires only manual labor to transport very heavy objects,weighing a ton or more.

In a hoist, the combination of a suitable support having a hollowspherical fulcrum, a beam supported on said fulcrum, its under surfacehaving a spherical cavity fitting closely on said spherical fulcrum, abolt tying the beam to the fulcrum and extending through a hole inthe'top of the fulcrum and having a round head within the fulcrum, saidbolt being secured rigidly with reference to the beam, but being movablewithin the fulcrum, means suspended from the outer end of one arm ofsaid beam for supporting an object to 'be transported thereby, and aplatform for counterbalancing weights supported upon the other arm ofsaid beam.
